Introduction to implementing front-end Paging for table and ul li in js

This article mainly introduces js to implement front-end Paging for table and ul li. If you need it, refer

The Code is as follows:

(Function ($ ){

$. Fn. tablepage = function (oObj, dCountOfPage, fresh_id ){

Var dPageIndex = 1;

Var dNowIndex = 1;

Var sPageStr = "";

Var dCount = 0;

Var oSource = $ (this );

Var sNoSelColor = "# CCCCCC ";

Var sSelColor = "black ";

Var sFontColor = "white ";

Var nowIndex = 1;

 

Change_page_content ();

 

Function change_page_content (){

// Obtain the data volume

DCount = oSource. children (). children (). length;

// The alarm rule is displayed.

SPageStr = "<div class = 'ref '> <a href = 'javascript: void (0)' id = 'fresh _"

+ Fresh_id

+ "'Onclick = 'fresh (this. id); 'class = 'sx 'style = 'color: #247AA9; '> <span> refresh </span> </a> </div> ";

SPageStr + = "<div class = 'msdn '> <a href = 'javascript: void (0)'> homepage </a> <a href = 'javascript: void (0) '> previous page </a> <a href = 'javascript: void (0)'> next page </a> <a href = 'javascript: void (0) '> last page </a> </div> ";

SPageStr + = "<div class = 'txt '>" + "Total" + Math. ceil (dCount/dCountOfPage) + "Page, current" + "<strong>" + dNowIndex + "</strong>" + "page" + "</div> ";

OObj.html (sPageStr );

DPageIndex = 1;

// Content in the internal table

Var rr = oSource. children (). children ("tr ");

OSource. children (). children ("tr"). each (function (){

// = 2

If (dPageIndex> = (dNowIndex-1) * dCountOfPage) + 1)

& DPageIndex <= (dNowIndex * dCountOfPage ))){

$ (This). show ();

} Else {

$ (This). hide ();

}

 

DPageIndex ++;

});

 

// OSource. children (). children ("tr"). first (). show (); // The head must show

If (dCount <= dCountOfPage ){

Var tt = $ ("# table_page _" + fresh_id). children ('. msdn'). children (). each (function (I ){

If (I = 2 | I = 3 | I = 0 | I = 1 ){

$ (This). addClass ("disabled ");

}

});

}

Else if (dNowIndex = Math. ceil (dCount/dCountOfPage )){

Var tt = $ ("# table_page _" + fresh_id). children ('. msdn'). children (). each (function (I ){

If (I = 2 | I = 3 ){

$ (This). addClass ("disabled ");

}

});

} Else if (dNowIndex = 1 ){

Var tt = $ ("# table_page _" + fresh_id). children ('. msdn'). children (). each (function (I ){

If (I = 0 | I = 1 ){

$ (This). addClass ("disabled ");

}

});

}

// Add a merge tasks event

OObj. children (). children (). each (function (){

 

$ (This). click (function (){

 

DNowIndex = $ (this) [0]. innerHTML;

If (dNowIndex = 'homepage '){

DNowIndex = 1;

Change_page_content ();

NowIndex = dNowIndex;

}

If (dNowIndex = 'last page '){

DNowIndex = Math. ceil (dCount/dCountOfPage );

Change_page_content ();

NowIndex = dNowIndex;

}

If (dNowIndex = 'Next page '){

If (nowIndex <Math. ceil (dCount/dCountOfPage )){

DNowIndex = parseInt (nowIndex) + 1;

Change_page_content ();

NowIndex = nowIndex + 1;

}

}

If (dNowIndex = 'preview '){

If (nowIndex> 1 ){

DNowIndex = parseInt (nowIndex)-1;

Change_page_content ();

NowIndex = nowIndex-1;

}

}

});

});

}

};

}) (JQuery );

 

The Code is as follows:

<Script type = "text/javascript">

$ (Document). ready (function (){

Var totalPage = $ ("ul li"). length;

Var total = Math. ceil ($ ("ul li"). length/5 );

Var current = 1;

// Var index = 4;

$ ("Ul li: gt (4)"). hide ();

$ ("# BtnPrev "). attr ("class", "tabs-scroller-left-disabled "). attr ("disabled", "disabled "). click (function (){

Debugger;

$ ("# BtnNext"). attr ("class", "tabs-scroller-right ");

$ ("# BtnNext"). removeAttr ("disabled ");

Current-= 1;

Var tt = current;

$ ("Ul li"). show ();

Var indexStart = (current-1 );

Var indexEnd = indexStart + 4;

$ ("Li: lt (" + indexStart + "), li: gt (" + indexEnd + ")", $ ("ul"). hide ();

If (current = 1 ){

$ (This). attr ("class", "tabs-scroller-left-disabled ");

$ (This). attr ("disabled", "disabled ");

}

});

$ ("# BtnNext"). click (function (){

$ ("# BtnPrev"). attr ("class", "tabs-scroller-left ");

$ ("# BtnPrev"). removeAttr ("disabled ");

Current + = 1;

$ ("Ul li"). show ();

Var indexStart = (current-1 );

Var indexEnd = current + 4 >$ ("ul li"). length-1? $ ("Ul li"). length-1: current + 3;

$ ("Li: lt (" + indexStart + "), li: gt (" + indexEnd + ")", $ ("ul"). hide ();

If (current + 4> = totalPage ){

$ (This). attr ("class", "tabs-scroller-right-disabled ");

$ (This). attr ("disabled", "disabled ");

}

 

});

} Else {
